Hi,

I am using webkit browser for my embedded linux platform with memory swap.

However, when I check the source code, I can see that MemoryPressureHandlerLinux.cpp does not consider swap memory.

Looking inside the MemoryUsagePoller function, we are only monitoring the VmRSS value.
So, in the Linux environment using memory swap (HDD swap, etc.), I confirmed that memory clear (garbage collection) is not done at the time I expect.

This will result in OOM of the platform in severe cases.
I'd suggest that not only the VmRSS values should be monitored, but also the VmSwap as well.
